kldload if_ath if will create ath0 which is a INET interface which
will invoke pccard_ether, which will configure the interface based on
what is configured in rc.conf. Point is, down the road wlan0 will be
created, with 2 things following
1. start wpa_supplicant if it is configured in rc.conf
2. create an event for devd which will again invoke pccard_ether for wlan0
So basically we have 2 instances of pccard_ether started, one for ath0
and one for wlan0.

create ath0 -> devd (new interface ath0) -> pccard_ether -> create
wlan0 (*) -> start wpa_supplicant
(*) devd (new interface wlan0) -> pccard_ether -> start wpa_supplicant

Hope that makes it a bit clearer.
